Description

[0002] The density of the new building materials slag powder and steel slag powder produced by the company is determined using the cement density determination method, with anhydrous kerosene as the liquid medium.

[0003] Previously, the density analysis of slag powder involved the traditional method of adding liquid: kerosene was added to the Leybold flask along the wall using a beaker or other glass vessel, and then the graduations were taken. This process resulted in powder adhering to the neck of the flask when the slag powder was added, affecting the accuracy of the measurement and the readings, and even rendering the experiment invalid.

[0004] This places certain demands on the key steps and details of our testing work, requiring us to further improve testing efficiency and find ways to prevent material from sticking to the bottleneck during the liquid addition process, so as not to affect data reading.

[0014] In one embodiment of the present invention, a horizontal plate is fixedly connected to the opposite surfaces of the first mounting bracket and the second mounting bracket, and a gear is rotatably connected to one side of the horizontal plate, with the first rack and the second rack meshing with the gear.

[0015] In one embodiment of the present invention, a connecting rod is fixedly connected to one side of the second rack, and a limiting ring is fixedly connected to one side of the mounting plate, and the connecting rod is slidably mounted on the inner surface of the limiting ring.

[0016] In one embodiment of the present invention, two third grooves are provided on the top of the mounting plate, a mounting ring is fixedly installed on the outer surface of the first electric telescopic rod, and a limit rod is slidably installed on the inner surface of the mounting ring.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0034] Reference Figure 1-8 As shown, a slag powder density measuring and liquid addition device includes a base 1, a turntable 2 rotatably mounted on the top of the base 1, and a weighing platform 75 fixedly mounted on the top of the base 1; it also includes a liquid addition mechanism for adding liquid to a container containing slag powder; the liquid addition mechanism includes a support block 4, which is fixedly mounted on the top of the base 1, a first threaded rod 41 rotatably mounted in the inner cavity of the support block 4, a second motor 42 fixedly connected to the top of the first threaded rod 41, the second motor 42 fixedly mounted on the top of the support block 4, an mounting plate 43 slidably mounted in the inner cavity of the support block 4, the mounting plate 43 being threadedly connected to the first threaded rod 41, a first electric telescopic rod 61 rotatably mounted on the top of the mounting plate 43, a cover plate 64 fixedly connected to the top of the first electric telescopic rod 61, and a syringe 6 movably mounted on the top of the mounting plate 43.

[0035] The traditional method of adding liquid involves using a beaker or other glass vessel to add kerosene along the bottle wall into the Leigh flask, and then reading the scale. However, this method can cause slag powder to stick to the bottle neck scale when it is added, affecting the accuracy of the measurement and the reading of the scale, and may even lead to the failure of the experiment.

[0036] In use, the present invention first places a container containing slag powder on top of the turntable 2, and then places a syringe 6 containing kerosene in the mounting hole at the top of the mounting plate 43. The output shaft of the second motor 42 drives the first threaded rod 41 to rotate. The rotation of the first threaded rod 41, together with the inner cavity of the support block 4, limits the mounting plate 43, allowing the mounting plate 43 to move up and down. At this time, the mounting plate 43 moves downward, causing the injection end of the first electric telescopic rod 61 to enter the inner cavity of the container. Then, the output end of the first electric telescopic rod 61 retracts, and the output end of the first electric telescopic rod 61 presses the syringe 6, thereby injecting the kerosene in the inner cavity of the syringe 6 into the container, achieving mixing.

[0037] Furthermore, such as Figure 2 and Figure 3 As shown, the base 1 has a first groove 11 on its top, the turntable 2 is rotatably mounted on the inner surface of the first groove 11, and the bottom of the turntable 2 is fixedly connected to a first motor 22, which is fixedly mounted on the bottom of the base 1.

[0038] The turntable 2 has three second grooves 21 on its top. Limiting posts 32 are slidably installed on the inner surface of the second grooves 21. A sliding rod 31 is rotatably connected to the top of the limiting post 32. Three limiting plates 3 are fixedly installed on the top of the base 1. The sliding rod 31 is slidably installed on the inner surface of the limiting plate 3. A first clamping plate 33 is fixedly connected to one end of the limiting plate 3.

[0039] In use, after the container is placed on top of the turntable 2, in order to prevent the injection end of the syringe 6 from touching the container wall and causing the container to shift during the process of inserting the injection end of the syringe 6 into the container, it is necessary to fix the container. The output shaft of the first motor 22 drives the turntable 2 to rotate in the inner cavity of the first groove 11. When the turntable 2 rotates, it will pull the limiting post 32. The limiting post 32 slides in the inner cavity of the second groove 21. The limiting post 32, along with the sliding rod 31, slides in the inner cavity of the limiting plate 3, thereby causing the three first clamping plates 33 to come closer to each other and clamp the container.

[0040] Furthermore, such as Figure 5 and Figure 6 As shown, a first mounting bracket 5 and a second mounting bracket 52 are fixedly installed on the top of the base 1. A first rack 51 is slidably installed on the inner surface of the first mounting bracket 5. A connecting plate 58 is fixedly connected to the top of the first rack 51.

[0041] A plurality of spring rods 521 are slidably mounted on the inner surface of the second mounting bracket 52, and the output ends of the plurality of spring rods 521 are fixedly connected to a second rack 53.

[0042] The first mounting bracket 5 and the second mounting bracket 52 are fixedly connected to a horizontal plate 54 on their opposite sides. A gear 55 is rotatably connected to one side of the horizontal plate 54. The first rack 51 and the second rack 53 are both meshed with the gear 55.

[0043] A connecting rod 56 is fixedly connected to one side of the second rack 53, and a limiting ring 57 is fixedly connected to one side of the mounting plate 43. The connecting rod 56 is slidably installed on the inner surface of the limiting ring 57.

[0044] The mounting plate 43 has two third grooves 431 on its top. The outer surface of the first electric telescopic rod 61 is fixedly mounted with a mounting ring 62, and the inner surface of the mounting ring 62 is slidably mounted with a limit rod 63.

[0045] When using this invention, when it is necessary to squeeze the kerosene out of the inner cavity of the syringe 6, the output end of the first electric telescopic rod 61 is contracted. The output end of the first electric telescopic rod 61 moves downward with 64, which allows the piston end of the syringe 6 to slide in the inner cavity of the syringe 6, thereby squeezing out the kerosene from the inner cavity of the syringe 6. When installing the syringe 6, the first electric telescopic rod 61 can be rotated to one side to avoid 64 affecting the installation of the syringe 6. During installation, the limiting rod 63 is pulled out from the mounting ring 62 and the inner cavity of the third groove 431 to avoid the limiting rod 63 affecting the rotation of the first electric telescopic rod 61. At the same time, inserting the limiting rod 63 into the inner cavity of the third groove 431 can fix the first electric telescopic rod 61.

[0046] In order to stably add kerosene into the container, the mounting plate 43 moves upward and drives the second rack 53 through the connecting rod 56. The second rack 53 further drives the first rack 51 to move downward through the gear 55. The first rack 51 and the connecting plate 58 move downward to squeeze the piston end of the syringe 6. When the syringe 6 injects kerosene into the container, the mounting plate 43 will move the syringe 6 upward. This can prevent the syringe 6 from contacting the liquid in the container and increase the stability when adding kerosene.

[0047] The relative positions of the second rack 53 and the first rack 51 need to be adjusted according to the extension length of the piston end of the syringe 6. Several spring rods 521 are connected to a side plate on one side. The side plate slides in the inner cavity of the second mounting bracket 52. The spring rods 521 are fixedly connected to the second mounting bracket 52. The spring rods 521 and the second rack 53 will not rotate relative to each other.

[0048] Furthermore, such as Figure 8As shown, the base 1 has a fourth groove 7 on its top. A third motor 71 is fixedly installed on the inner surface of the fourth groove 7. The output shaft of the third motor 71 is fixedly connected to a second electric telescopic rod 72. The output end of the second electric telescopic rod 72 is fixedly connected to a third mounting bracket 73. A second threaded rod 731 is rotatably installed on the inner surface of the third mounting bracket 73. One end of the second threaded rod 731 is fixedly connected to a fourth motor 732. The fourth motor 732 is fixedly installed on one side of the third mounting bracket 73.

[0049] A slider 734 is slidably mounted on the inner surface of the third mounting bracket 73. A third electric telescopic rod 74 is fixedly connected to one side of the slider 734. A fourth mounting bracket 741 is fixedly connected to the output end of the third electric telescopic rod 74. A bidirectional threaded rod 745 is rotatably mounted on the inner surface of the fourth mounting bracket 741. Two second clamping plates 742 are slidably mounted in the inner cavity of the fourth mounting bracket 741. Both second clamping plates 742 are threadedly connected to the bidirectional threaded rod 745. A fifth motor 747 is fixedly connected to one end of the bidirectional threaded rod 745. The fifth motor 747 is fixedly mounted on one side of the fourth mounting bracket 741.

[0050] In use, to facilitate and stably remove the container filled with kerosene from the top of the turntable 2, the output shaft of the third motor 71 drives the second electric telescopic rod 72 to rotate. The second electric telescopic rod 72 drives the third mounting frame 73 to rotate. The third mounting frame 73 further moves the two second clamping plates 742 to the top of the container, positioning them on both sides. Then, the second electric telescopic rod 72 retracts, causing the second clamping plates 742 to move down to a position where they can clamp the container. Next, the output shaft of the fifth motor 747 drives the bidirectional threaded rod 745 to rotate, which in turn drives the two second clamping plates 742 to clamp the container. Then, the output shaft of the fourth motor 732 drives the second threaded rod 731 to rotate, which in turn drives the slider 734 to slide along the fourth mounting frame 741. Combined with the rotation of the third mounting frame 73, the container can be transferred to the top of the weighing platform 75 for weighing.

[0051] Working principle: First, the container is placed on top of the turntable 2. Then, the output shaft of the first motor 22 drives the turntable 2 to rotate. The second groove 21 slides with the limiting post 32 and the slide rod 31. The slide rod 31 clamps the container with the first clamping plate 33. Then, the mounting plate 43 moves the syringe 6 to move the injection end of the syringe 6 to the top of the container. Then, the first threaded rod 41 rotates to drive the injection end of the syringe 6 to move into the inner cavity of the container. During this process, the spring rod 521 is squeezed, causing the second rack 53 to separate from the gear 55, so that the connecting plate 58 is close to the piston end of the syringe 6. Then, the second rack 53 is engaged with the gear 55. At this time, when the mounting plate 43 moves, it will move the second rack 53 through the connecting rod 56. The second rack 53 moves downward through the gear 55 with the first rack 51 and the connecting plate 58, thereby squeezing the piston end of the syringe 6 and squeezing the kerosene in the inner cavity of the syringe 6 into the container.

[0052] After the kerosene is added to the container, the output shaft of the third motor 71 drives the second electric telescopic rod 72 to rotate. The second electric telescopic rod 72 drives the third mounting frame 73 to rotate. The third mounting frame 73 further moves the two second clamping plates 742 to the top of the container and positions the two second clamping plates 742 on both sides of the container. Then, the second electric telescopic rod 72 retracts, causing the second clamping plates 742 to move down to a position that can clamp the container. Then, the output shaft of the fifth motor 747 drives the bidirectional threaded rod 745 to rotate. The bidirectional threaded rod 745 can drive the two second clamping plates 742 to clamp the container. Then, the output shaft of the fourth motor 732 drives the second threaded rod 731 to rotate. The second threaded rod 731 drives the slider 734 to slide with the fourth mounting frame 741. With the rotation of the third mounting frame 73, the container can be transferred to the top of the weighing platform 75 for weighing.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
